Big IQ and HA Sync
I configured by developers the ability to use BIG-IQ to take pool members in/out of load when they do maintenance. I am using role based access (RBAC) and configured each user the ability to see only the pool/pool members/nodes they manage. Our ADC's are also part of an HA pair. The ADC's are either a -1 or a -2. In BIG-IQ, they are placed into a cluster group that allows synchronization. Using RBAC, I configured the user to see only see the -1 just so that they are not overwhelmed by seeing all of the members of both ADC pairs in BIG-IQ. Some users control many pools and members. When they take a pool member out of load, the status reflects in BIG-IQ and BIG-IQ automatically synchronizes the HA pair. The only caveat in the BIG-IQ procedure is if a user wants to change the status (enable, disable, or force-offline) of more than one pool member at once, BIG-IQ will synchronize the HA pair after each status change. So for example, if a user wants to disable 5 pool members, expect BIG-IQ to perform 5 HA pair synchronizations. One after each pool member status change. This behavior is not so bad if a user is only changing a couple nodes but if you have many, a delay is expected in the maintenance procedure.
